Just waiting on parts . . . SOL

Parts are getting harder to get.  NOS, aftermarket, swap meet, it doesn't matter.  As the craze of rebuilding all this old stuff gets even crazier . . . parts are drying up.  You almost need to stock-up if you plan on doing this for a living.  I just do it for friends, etc . . . but, if you had a shop where you were really trying to pump out some work - you'd be screwed . . . no parts.  Backordered.  OOS(Out-of-Stock).  S.O.L. !
